This is a good basic computer package . It's got a good CPU , 256 megabytes of RAM , and a DVD player .   Does it come with a modem ?   Yes , it has a built-in modem . You just plug a phone line into the back of the computer .   How about the monitor ?   A 15 - inch monitor is included in the deal . If you want , you can switch it for a 17 - inch monitor , for a little more money .   That's okay . A 15 - inch is good enough . All right , I'll take it .
